If the air filter in your truck is dirty will conditioner not blow cold air?
No, the air filter in your truck does not affect the operation of the air conditioner. The air conditioner has its own filter that removes dust and debris from the air before it is cooled and circulated through the cabin. If the air conditioner is not blowing cold air, it is likely due to a problem with the refrigerant, compressor, or other components of the air conditioning system.
